The apartment is about 30-40mins taxi ride (210 THB) from Don Muang International Airport. Very close by to the Chatuchak Market, roughly 100THB taxi ride.
To get to the main road takes about 10mins by foot, and about 20-30mins by taxi to the city area (Siam Paragon etc).
The apartment is new and was in good condition when we checked it. Do note that the apartment building does not have an elevator so if you are traveling with elderly persons, children or have heavy bags, do choose the units on the lower floor.
Tony was helpful and prompt in his response when I asked for suggestions about where to visit.
Overall, good experience.
